Question

I have installed numpy1.3,scipy 0.7.1,matplotlib 0.99.1.1 and python 2.5 when I import pylab I get the following error. Someone please help.

 /var/lib/python-support/python2.5/gtk-2.0/gtk/__init__.py:72: GtkWarning: could not open display
      warnings.warn(str(e), _gtk.Warning)

尝试使用不同于Gtk的背书进行策划。

1. 开放 p虫和类型:

>>> import matplotlib
>>> matplotlib.matplotlib_fname()

This will print a file name. Edit this file and modify the section Backend and change Gtk or GtkAgg with any other (see the documentation in the same file), until you get it working. You can find more information about backends here.

至于为何在你试图使用背书时出现错误,这取决于你是如何安装图书馆的,以及你在电脑上安装的。我建议安装同异构体/异构体的校正,并选择所有选用地。
